P2087 Code - Exhaust Gas Temperature Sensor Circuit Intermittent Bank 2 Sensor 2
Quick Answer
The P2087 diagnostic trouble code refers to an issue with the Exhaust Gas Temperature (EGT) sensor circuit on Bank 2 Sensor 2 in a vehicle's exhaust system. Common causes include Faulty EGT Sensor: The most common cause of the P2087 code is a malfunctioning EGT sensor itself, which may be due to wear and tear or electrical issues, Wiring or Connector Issues: Damaged wiring or poor connections in the EGT sensor circuit can lead to intermittent faults and trigger the code, Exhaust System Leaks: Leaks in the exhaust system can affect the sensor's readings, causing the code to be triggered. Severity is Low - monitor the vehicle and repair when practical. The vehicle can usually be driven if no severe symptoms are present, but symptoms should be checked before extended driving.

Code P2087 Description
The P2087 diagnostic trouble code refers to an issue with the Exhaust Gas Temperature (EGT) sensor circuit on Bank 2 Sensor 2 in a vehicle's exhaust system. This sensor is responsible for monitoring the exhaust gas temperature to ensure optimal performance and emissions control. When this code is triggered, it indicates that there is an intermittent fault in the circuit, which can affect the vehicle's performance and emissions output.
Common Causes of P2087
- Faulty EGT Sensor: The most common cause of the P2087 code is a malfunctioning EGT sensor itself, which may be due to wear and tear or electrical issues.
- Wiring or Connector Issues: Damaged wiring or poor connections in the EGT sensor circuit can lead to intermittent faults and trigger the code.
- Exhaust System Leaks: Leaks in the exhaust system can affect the sensor's readings, causing the code to be triggered.
- ECM Malfunction: A malfunction in the engine control module (ECM) can also lead to intermittent faults with the EGT sensor circuit.
- Other Sensor Malfunctions: Issues with other sensors in the engine management system can indirectly affect the EGT sensor circuit and trigger the code.
Symptoms of P2087
- Check Engine Light: The most common symptom associated with the P2087 code is the illumination of the check engine light on the vehicle's dashboard.
- Reduced Engine Performance: A faulty EGT sensor can cause the engine to run erratically, leading to reduced power and acceleration.
- Poor Fuel Efficiency: Incorrect temperature readings from the EGT sensor can result in inefficient fuel combustion, leading to increased fuel consumption.
- Rough Idling: A faulty EGT sensor may cause the engine to idle roughly or inconsistently.
- Emission Issues: The vehicle may fail emissions tests due to increased emissions caused by the incorrect fuel mixture.
How to Fix P2087
- Diagnostic Testing: Begin by using a diagnostic scanner to read the code and pinpoint the exact cause of the issue.
- Inspect EGT Sensor: Check the EGT sensor on Bank 2 Sensor 2 for any physical damage or signs of malfunction.
- Check Wiring and Connections: Inspect the wiring and connectors in the EGT sensor circuit for any damage or corrosion.
- Replace EGT Sensor: If the sensor is faulty, replace it with a new, OEM-approved sensor to ensure accurate readings.
- Clear Codes: After completing the repair, clear the diagnostic trouble codes and test drive the vehicle to verify that the issue has been resolved.
Cost to Fix P2087
The cost of repairing a P2087 code can vary depending on the make and model of the vehicle, the location of the repair shop, and the specific parts needed for the repair. Typically, the cost of a new EGT sensor can range from $100 to $300, while labor costs can amount to $100 to $200. Overall, the total repair cost for addressing a P2087 code can range from $200 to $500. It is advisable to consult with a qualified mechanic or repair shop to get an accurate estimate based on the specific circumstances of the vehicle.

Frequently Asked Questions about P2087 Code
What does the OBDII code P2087 mean?
P2087 indicates an intermittent issue with the exhaust gas temperature (EGT) sensor circuit on Bank 2, Sensor 2, which monitors exhaust gas temperature downstream of the catalytic converter.
What are the common symptoms of code P2087?
Symptoms may include the check engine light turning on, poor engine performance, increased emissions, and reduced fuel efficiency.
What causes code P2087 to be triggered?
Common causes include a faulty EGT sensor, damaged wiring or connectors, excessive soot buildup on the sensor, or an issue with the sensor's circuitry.
Can driving with code P2087 cause damage?
While driving with this code may not immediately damage the vehicle, prolonged issues could lead to increased emissions, reduced fuel efficiency, and potential damage to the catalytic converter.
How can I diagnose code P2087?
Diagnosis typically involves inspecting the EGT sensor, checking the wiring and connectors for damage or corrosion, and using a multimeter to test the sensor's circuit for continuity.
How is code P2087 fixed?
Repairs may include replacing the faulty EGT sensor, repairing or replacing damaged wiring, cleaning the sensor if it’s clogged with soot, or addressing circuit malfunctions.
Does code P2087 affect emissions?
Yes, a malfunctioning EGT sensor can lead to incorrect exhaust temperature readings, which may cause increased emissions and inefficient combustion.
